1939 Jrnl. Amer. Chem. Soc. 61 2392/1 The luminescence which appears when sound waves pass through liquids has been called acoustic or sonic luminescence, for short, sonoluminescence.
1976 Jrnl. Acoustical Soc. Amer. 60 103/2 The sonoluminescence from a gas dissolved in water is inversely proportional to the thermal conductivity of the gas.
2005 Nature 27 Oct. 1224/3 Overnight, sonoluminescence became a cottage industry in the world of acoustical physics.
